Vertical Round Muffler for Massey Harris 55, 55D, 55K & 555 Tractors

Description

When your vintage Massey Harris starts sounding more like a steam engine than the reliable farm tractor it should be, that’s usually a sign your muffler has given up the ghost. These classic tractors from the ’40s and ’50s deserve proper exhaust components to keep them running quietly and efficiently. This replacement muffler brings back the civilized operation these workhorses had when they first rolled off the assembly line.

What You’re Getting

• Durable 6-inch round body construction built to handle the heat and vibration of farm work
• Vertical mounting orientation that matches your original factory setup
• Proper inlet and outlet sizing ensures good exhaust flow without back pressure issues
• 21-inch overall length with quality internal baffling for effective sound reduction
• Heavy-gauge steel that resists rust-through and maintains performance season after season

Built for Real Farm Work

This muffler fits the Massey Harris 55, 55D, 55K, and 555 models that were the backbone of many farming operations through the ’40s and ’50s. These tractors handled everything from cultivating and planting to belt work and general farm chores, often running long hours during busy seasons. They’re still popular today with collectors and farmers who appreciate straightforward, fixable machinery that gets the job done.

Made to Last

Vintage tractor mufflers face the same challenges as modern ones—constant heat cycling, moisture, and the bumps that come with field work. This replacement is built with materials that stand up to these conditions while maintaining the proper exhaust flow your engine needs to run efficiently and cleanly.

Good to Know

This muffler mounts vertically like the original, so installation uses your existing mounting hardware and exhaust connections. Before installing, check the condition of your exhaust pipe and mounting clamps—after decades of use, these often need attention too. A little penetrating oil on old clamps makes removal much easier, and new gaskets ensure a leak-free seal.
